5. Insert the 4 large closure screws through the cover. Fasten two screws (left or right) approximately 2cm into the box. The cover can then be opened to the side.
6. Perform a trial closure of the box. If the lid does not close completely, the box is not fitted evenly to the wall and requires adjustment. Ensure the box is waterproof when closed.

Wiring of Control / Summary

General Wiring Steps:

• Start with the 230V supply cable, running it through the large cable bushing on the left side.
• Attach a cable eye to the ground wire and connect it to the base plate with a washer and nut.
• Connect all other cables to the control board.

Cables and Wiring Recommendations

Using shielded cable for motor-to-control board connections is highly recommended to prevent electrical noise and interference. Avoid running 230V and low voltage cables in the same power line. Use separate cables for infrared sensors, switches, flashing lamps, electric locks, and other wiring like telephone or garden lights. Flexible cables are preferred over rigid copper cables for easier installation. Ensure cable material is suitable for outdoor use and underground installation; use conduits if necessary. Consult a local electrician for specific requirements.

Recommended Accessories for Cabling:

• LA400-JB40E Kit: 12m of 6-pole cable, distribution box IP65, cable screw joints, and fastening material.
• 041ASWG-0482-50 Cable: 50m for professional use, 6-pole cable.

Advanced Features and Settings

Photocells (Models: 771E, 772E)

Photocells are essential for gate safety and must be used according to EN12453 standards. They consist of a transmitter and receiver, typically mounted opposite each other at a height of 200 mm. The Chamberlain failsafe photocell system uses a 2-cable setup with visible LEDs indicating status. The manual details sensor programming, deletion, and diagnostic indicators for photocells and the control board.

Radio and Radio Programming

The receiver has two channels (CH1, CH2) for controlling one or both wings. Programming involves setting the DIP "RADIO" switch, pressing a button on the control board (P1 for CH1, P2 for CH2), and then pressing and holding a button on the remote control until the LED confirms programming. Up to 85 remote controls can be programmed per channel. To delete all programmed remotes, press and hold the learn-button P1 for approximately 10 seconds with DIP "RADIO" switched on.

Program Internet Gateway myQ

To connect the myQ system:

1. Connect the Internet Gateway to your router via Ethernet cable and connect power.
2. Create an online account via the Liftmaster MyQ smartphone app or website (www.liftmaster.eu).
3. Register the Internet Gateway and follow the on-screen prompts to add the gate opener as a new device.
4. The system will confirm successful programming and prompt you to name the gate.

Program Door Monitor

To program the Door Monitor:

1. Connect power to the door monitor and place it in a visible location.
2. Press and release the "LEARN" button on the door monitor (LEDs blink alternately).
3. Within 60 seconds, press and release the RESET button on the control board. Confirmation is indicated by solid red and green LEDs on the door monitor.

Delete Door Monitor: Press and hold the "LEARN" button on the door monitor for at least 10 seconds. A beep confirms deletion.

Loop Detector

Loop detectors react to metal, commonly used for vehicles. They can be configured as an exit loop (opens gate when closed, keeps it open, or re-opens) or as a safety/interrupt/shadow loop. For exit loops, DIPs OPEN/STEP and LOOP/EDGE must be ON, and photocells are required. Safety loops do not comply with regulations as single protection for people. The manual provides details on DIP switch settings (OPEN/STEP, LOOP/EDGE) and wiring connections for loop detectors.

DIP Settings

Various DIP switches on the control board configure the system's behavior:

• 1/2 Motor: Selects between 1 or 2 motors connected.
• OPEN/STEP: Controls gate programming and reaction to commands (Step Mode or OPEN Mode).
• LIGHT/SPY: Selects between yard lighting (OFF) or gate monitoring (ON).
• OBSTACLE: Disabling the wire jumper increases operating power but requires additional safety devices.
• LOOP/EDGE: Selects between EDGE (OFF) or LOOP (ON) detection.
• SPEED: Selects motor speed (Slow for ART, LYN, SCS, SUB; Fast for LYN, SCS, SUB).
• RADIO: Required for programming remote controls. Must be switched OFF when not in use.

Wing Delay Adjustment

This feature adjusts the delay between the closing of two wings to ensure proper operation and safe spacing. The delay is adjustable by pressing P3 and P1 together for approximately 5 seconds. The number of clicks heard from a relay indicates the delay level (1 click = small delay, 2 clicks = medium delay, 3 clicks = big delay, 4 clicks = total delay, 5 clicks = no delay). The opening delay is fixed at 3-5 seconds.

Initial Operation and Programming

Basic Setting Procedure

Follow these steps for initial setup:

1. Ensure all components (motors, photocells, safety contact strip, stop switch) are connected.
2. If using a single gate wing, set DIP "1 / 2 Motor" to ON.
3. Ensure no one is in the gate's path.
4. Close the gate(s) and attach the motors.
5. For ART operators: Adjust reference point "passpoint" cams for successful travel distance programming. Ensure micro-switches are not pushed simultaneously or at the end position. Use pliers or a flat screwdriver for adjustment. Disengage the gate using the release key.
6. For SUB operators: Set DIP SPEED ON for faster movement or OFF for heavier gates/safer operation.
7. For LYN-SCS operators: Set DIP SPEED ON for faster movement or OFF for heavier gates/safer operation.
8. Connect the mains supply (230V) to the control board.
9. Basic Setting: Press P1, P2, and P3 simultaneously for 2-3 seconds until the yellow LED flashes.
10. Press and hold P1 for 1-2 seconds to open motor 1. If it closes, reverse red and blue motor wires (disconnect power first). Repeat step 1 and 2. Leave gates partially open.
11. Press and hold P2 for 1-2 seconds to open motor 2. If it closes, reverse red and blue motor wires (disconnect power first). Repeat step 1 and 2. Leave gates partially open.
12. Note: The control board is active for manual setting for approx. 20 seconds.
13. Final Checks: For SCS models, ensure the front housing does not touch the gate during opening. For all models, ensure both wings open completely without over-extending. For SUB operators, adjust the hard-stop in the box.
